Give them time and lots of water. You will have more flowers I'm sure of it.

There's time yet. Mine are just beginning to flower now. I do find the sparrows pick off the flowers though, so I hang up windmills and old cds to scare them. In dry spells many people spray the flowers with water to help the beans set.

Thanks to both, I have given them a good drenching will see how they get on,thanks again
